Our cellular kinase assays have been designed to measure compound activity in a physiological environment on a physiological substrate. Cellular kinase assays are therefore a crucial part of rationale drug development.

Cellular proliferation assays are widely used and accepted in oncology as an initial screen in the transition phase from biochemical screens to biological relevant models. ProQinase's CL40-ProliFiler and CL100-ProliFiler are standardized service packages comprising IC50 determination of one test compound against a defined panel of 40 or 100 cell lines. In addition, ProQinase offers free choice cell proliferation assay services with definition of the number of test cpds and cell lines according to your requirements.

Anchorage independent growth of cells in soft agar is one of the hallmark characteristics of cellular transformation and uncontrolled cell growth, with normal cells typically not capable of growth in semisolid matrices. Testing drugs in a 3-dimensional (3D) format, like soft agar, is considered superior to using monolayer cultures because cell growth in 3D is more similar to the in vivo cellular environment.

Cell migration is a hallmark of tumor formation and metastatic spreading. The process of cell movement is induced by various agents such as growth factors and chemokines and is associated with complex signaling which involves many components of the cellular motility machinery. The cell migration assay is ideally suited to test the anti-migratory efficacy of test compounds.

This service can be used to analyze the effect of test compounds on three-dimensional cell clones either with mono-spheroids of only tumor cells or with co-spheroids of tumor and stroma cells. Since tumor and stroma cells are labelled with different luciferases the effect of test compounds on tumor and stroma cells can be analyzed separately.

Angiogenesis, the formation of new blood vessels from pre-existing ones, is a physiological process during growth and development. Beyond that angiogenesis is mandatory for tumor growth and is involved in other pathological disorders (e.g. psoriasis, macular degeneration). The cellular angiogenesis assay mimics the in vivo situation with respect to the first stages of the angiogenic cascade. The assay allows the evaluation of potentially pro- or anti-angiogenic compounds or biologicals.
